,application mea ruiy 26,

`The invention relates to windowsfor dwellings, residences and the like, `and. the object ofthe invention is to provide a Window which may be opened and closed inthe conventional vmanner-of sliding the sasheS` of said windowy upwardly and downwardly respectively and which may at the same time be opened by swinging saidf'sashes about vertical hinges. y

A further object of the inventionV is to provide such' window with 'a mechanism, whereby one of the counterweiglitsusually attached', to the movable .window sash may ybe selectively connected to said `sash orto -the stationary window frame.v

Other objects of the -invention not specifi-l cally mentioned may be easily ascertained v and understood from the following specification and the accompanying drawings form- -ing'a part thereof.,l

In the drawings: f l y Fig. 1 is fanelevation of a window according to the: invention, aportion of the window frame being broken away .to show the constructionof a part of theftransferimechanism. f c

Fig. 2 is a horizontal cross'section'on line 2 2 of Figil. Fig. 3 isa detail drawing 'in a larger scale of the holder plate of the transfer mechanism.l l Y Y' Fig. 4 is an enlarged view of the transfer mechanism.; v Fig. 5 is a section online `5 5 of Fig. 4. The window has a stationary frame 6 and two 'sashes 7 and 8zrespectively, which are adapted to be slidably moved in said frame.

The frame may be of any suitable construc- 1 tion, as long as it is provided with the usual vertical guiding grooves 9, 10,: 11, and 12 respectively. Pulleys 13, 14,' 15 and-16: are rotatably mounted in said frame,'and cables 17,18, 19, and 20 aretrained over there- Vspective pulleys." Counterweights 21, 22,v

VSaid guide platesr 26'` and 27 Y are adaptedto engage the"V guide grooveslO I and'9 respectively.. Femalehinge parts 28 60 and '29 are provided on eachfof said sash frames on the above-identified side thereof. Corresponding male hinge vparts are fastened to stationary frame in such a manner, that the female hinge parts on'the lower sash 7 65 are in engagement with V'the corresponding maleghinge parts, when the sash is in-its lowermostrposition in the stationarynframe, i. e.\in closed position.-l The other set .of v male hingefparts are fastened to the {star70 ,tionarv frame in such: a manner asto'engage 4the female hinge partson the upper` sash, when said sash is slid down toits 'lowermostposition in thestationary frame, f

i. e. vwhen said sash is in open position.

The construction of the mechanism provided on the sasli fra-ine on the side opposite to'y the l"hinges kisfor `both rsashes the same,

scribed therefore. y V

The sash frameis somewhat hollowed Vout' to receive `the mechanism described inthe.

following, and al finishing board 32 covers said mechani'snnwith the exception' of'acylinder 33, which is rotatably arranged ifi/:S5

.the sashframe-and extendsinto a hole (not shown) provided therefor in the finishing board. lSaid. cylinder has'in its uncovered end polygonal hole 34 adapted to `receive a correspondingly shaped removable key 9e (not shown) forrotating said'cylinder. An arm' 35 is rigidly connected tothe cylinder, and a link 36 ispivotally jointed to said arm.I A lever ,37j ispivotally mounted onl Vsaid link, theconnection being effected vinter- 'e5 f mediate'the `ends of said lever. LA plate 38 is, fastenedto :thesashframefand one end 'of the `lever 37 is fastened pivotally tosaid f plate. The' other end of said'lever is pivotally .connected to a flatguidingbar39 adimi jacent the one end thereof.v 1A' lever V40is pivotally connected to the bar 39 adjacentVV i the otherY end thereof,and'th'e lever 4()v is pivotally lconnected 'with'. itsother end to -a .plate 41 fastenedtosash frame. `By rotat- 105 ing said' cylinder in onel direction'tlie flat bar 39 willbehprojected into'engagement with the guide groove 12 or ll'respectively according to which sash the mechanism is attached to, andbyrotation of the' cylinder liu.

- inthe other direction the guide bar will be retractedf, soVv that the sash will. be disengaged from theA stationary frame As stated above the innerV ends of the cables 19 and 20 are fastened each ,to a

w holder 'plate 25. As long as the sashl is in l, positionfor sliding movement in the stag.- i ytionary frame, the holder plate is in engageinent with a hook 42* Vfastened to vthe sash. For ,this purpose the plate has a rectangular opening 43 therein adapted torreceive vthe ,hook` 42.

"Inf order .toperinit` the sash to bev swung open about Vthel hinges it is necessaryV to release the sash from its connectionfwitli the count-erweiglfit 23 or 24, Vand in order t0 prevent at the saine time said weight from falli-iig down another hook 45 with a, linger 46"V is' fastened to ythe stationary frainey in such a position, thattlie hooks 42 and'45 w'i-ll'be located at thev same height, Vwhen the V l female hinge parts on the sash are in en'- VgaigeiiieiitA with the corresponding male parts. At the saine-V time the lingers 44V -w and 46'wi1l be arranged so, that'the one is '.Tov tranfer the holder plate vfrom hook Y i 42 to hook 45', when the sash is'to be swung opera-.or 'vice' versa, whenV the sash' is to be slidingly moved, a transfer plunger 47 is Y provided havinga stein 48 pivotally con- Vnientifoned arm nested to an Varm 49 rigidly fastened-to the cylinderv 33. VSaid arm r,is arrangedion the cylinder diainetrically opposite of the 'above A117 aiigle'shaped slot 50 is provided in the 'I holder plate25 as shown in Fig; 3, forming afinger 51 and a: cam surface 52'.' The trans-y fer plunger has acircularieind iiange53V and spaced therefrom anothercircular flange 54. The plunger portion between said flanges is adapted to slide .through the opening in the plate 25'bet`ween the :finger 51 and vsurface 52, so that the` Iflanges lwill be arranged one at each side of the plate' f Y V SUPpOSiDgthe sash has .been'moved into Vits lovvermost' position, and the female hinge .parts ont-lie sash aireieng'aged by vthe `inale and in engagement with vthe groove 11 `or l12; the .holder plate "25 'isrlield by the hook :42 fon they sash,` so vthat the couiiteriveightis Y connected rwitlithe sash.
